This online calculator computes length of angle bisector given the lengths of triangle edges (see the picture). Triangle vertices are usually named A, B and C. Triangle edges - a, b, c, where letter denotes opposite vertex. That is edge between A and B is named c, between A and C - b, between B and C - a.
The length of С's angle bisector shown on picture is:
L=\frac{\sqrt{ab(a+b+c)(a+b-c)}}{a+b}
